Currently > there are several platforms that could use it with DSI as well, e.g. In case that some board with DSI bus needs this LVDS bridge, the bridge type would be MIPI-DSI to LVDS Display bridge. So I think moving this lvds stuff into eDP driver is reasonable becasue the normal DSI bus cannot use this LVDS bridge, and this bridge (eDP to LVDS) would be for eDP bus. BTW, Sean, why not implementing this lvds codes to eDP driver without previous related patch? that seems unnecessary work. > Trats, Trats2, Arndale.

I also thought a better way is to use simple abstraction layer. But the abstraction layer I thought was the case that lvds binding is done in this lvds driver itself so drm connector should call some bridge related functions of the abstraction layer. But it seems that other maintainers don't agree to this way. :( Anyway, we can say the use of lvds bridge is dependent on board but actually, the use of lvds bridge would be more dependent on bus device or lcd panel attached to the board. So my opinion is to bind dt in the bus or lcd panel drivers that need lvds bridge. If dt binding of lvds bridge cannot be done itself, Sean's way is reasonable to me except the unnecessary patch.
